The cardiovascular market research reports by iData cover Interventional Cardiology, Cardiac Surgery, Cardiac Rhythm Management and the Electrophysiology market. The fastest growing segments within interventional cardiology are expected to be driven by new technologies, such as CTO crossers, FFR guidewires and OCT catheters. The vascular access market will grow due to a combination of increasing patient population and the shift towards technologically advanced devices that will continue to gain market share at the expense of older, less expensive devices. iData’s cardiovascular device market reports also include cardiac surgery, cardiac rhythm management, and other cardiovascular devices and procedures. Check out our different cardiovascular device market reports below.
Industry Trends There is a risk that the placement or introduction of a device during an interventional coronary procedure can dislodge thrombi or emboli, which could create health risks for the patient that the interventional procedure is intended to prevent. In response to these concerns, many different approaches were taken to deal with this problem,
The vast majority of IVUS catheters are used immediately before, during or after an angioplasty procedure. Intravascular ultrasound (IVUS) catheters are used in conjunction with minimally invasive cardiovascular procedures. Procedures utilizing IVUS catheters must be performed in catheterization laboratories or cath labs that have an IVUS console. These consoles are typically integrated into the cath lab infrastructure and are not portable. The introduction of IVUS consoles to an increasingly large percentage of cath labs in Japan, as well as the introduction of reimbursement programs for IVUS devices, allowed the number of IVUS catheters used to grow rapidly since 2002.
Optical coherence tomography (OCT) is an imaging modality that can create extremely high resolution three-dimensional images of biological tissues and has proven to be very effective for interventional purposes. While OCT has been used for a number of years in other medical fields, such as in ophthalmology, it has only recently been applied to cardiology. In 2017, only a few OCT systems were approved by the FDA for use in cardiology. However, OCT systems were being used for producing high resolution images of arteries in a clinical setting since 2006 in Japan and Europe.
Interventional guidewires are often the first type of device to cross an arterial lesion. For this reason, the choice of guidewire is extremely important in order for a procedure to be successful. Interventional guidewires used for coronary applications can be classified into two general types: conventional and specialty guidewires. While conventional guidewires are used for the most common types of procedures, specialty guidewires are used in cases where the lumen is occluded and a conventional guidewire is unlikely to be successful.
Introducer sheaths facilitate the insertion of devices such as guidewires and catheters for use in interventional procedures. They are tube-shaped and are generally inserted by nurses. Introducer sheaths can also simplify the application of patches and closure devices at the end of procedures to allow hemostasis to occur. Introducer sheaths are sold in a wide range of sizes to fit patient requirements. They need to have kick resistance and an elongated shape that protects vessels from injuries. In addition, introducer sheaths need to have a transparent structure to allow visualization. They are made with lubricated material to minimize the force and pressure during application. These characteristics make patient management much easier for nurses, and the introduction of devices smoother for doctors.
Fractional flow reserve (FFR) is a guidewire-based procedure that can accurately measure blood pressure and flow through a specific part of the coronary artery. FFR guidewires are inserted through a diagnostic catheter during a coronary angiogram. While FFR was still used in only a small percentage of angiography procedures, it is useful in assessing whether or not to perform angioplasty or stenting on borderline blockages. FFR provides data that is complementary to information from standard diagnostic guidewires and imaging systems.
Interventional catheters are used by physicians in procedures for the placement of devices such as stents and balloons. There is a large variety of catheters, and their use depends on the size, shape and curvature of the lesion. Cardiologists tend to choose catheters based on their guidewire selection. Interventional catheters must be rigid without being stiff, because the device must adapt itself to the curvature of certain arteries. In addition, catheters must promptly react to a physicians movements, sometimes following zigzag patterns, without risking puncturing the lumen.
Vascular closure devices (VCDs) are used in both the peripheral and coronary markets for minimally invasive cardiovascular therapies, which has created a large market for post-procedural VCDs. The introduction of a catheter into the arterial system, to place a stent for example, is much less traumatic for the patient than a comparable surgical intervention, with only a hole created in the artery (generally the femoral) for access. This access hole will bleed profusely if unmanaged, and therefore some form of vascular closure is required.
The primary uses of balloon-inflation devices are to inflate dilation balloons for stent placement as well as to inject contrast agents for use in diagnostic procedures. Balloon-inflation devices usually consist of a syringe, and sometimes a pressure gauge and a tube to connect the inflation device to the balloon catheter. Balloon-inflation devices are commonly designed to be inflated and deflated with one hand, allowing them to be operated very easily by just one person. Sometimes balloon-inflation devices can be used with self-expanding stents to confirm that they are seated properly and in no danger of moving. In general, balloon-inflation devices (also known as indeflators) consist of a syringe with a manometer or pressure reading instrument and a mechanism that controls the emptying and filling of the syringe. It is possible for dilation balloons to be inflated manually through the use of a simple syringe instead of a balloon-inflation device. However, when dilation balloons are inflated manually, it is not possible to monitor and control the pressure inside of the balloon. Proper monitoring of the pressure inside the balloon is important. If the balloon pressure is too low, the stent may not be completely deployed. If the balloon pressure is too high, there is a risk that the balloon will rupture.
The first devices used in the field of interventional cardiology were percutaneous transluminal coronary angioplasty (PTCA) balloon catheters. If it was not because of subsequent restenosis occurrences, they would still be the only device necessary for atherosclerosis treatment. Restenosis was the major problem plaguing interventional cardiology before stents were developed.
The dialysis catheter market is composed of short-term (acute) hemodialysis, and long-term (chronic) hemodialysis. The largest segment in the total dialysis catheter market in 2016 was represented by short-term hemodialysis catheters. The second largest market is the long-term hemodialysis catheters. The value of the total dialysis catheter market is expected to grow slightly over the forecast period.
The Japanese market for implantable ports comprises conventional implantable ports and power-injectable implantable ports. Conventional implantable ports are defined as implantable ports that do not feature power-injection. The Japanese market for implantable ports has been contracting due to a shift away from conventional and towards power-injectable implantable ports. This is further amplified as a result of strong declines in ASPs for power-injectable implantable ports as competitors are expecting strong growth for this segment.
The Japanese market for peripherally inserted central catheters (PICCs) is split into two segments: power-injectable and non-power-injectable PICCs. Non-power-injectable PICCs are defined as PICCs that do not feature power-injection or antimicrobial properties. Although power-injectable PICCs have become the standard of care in some countries such as the United States, Japan still prefers conventional PICCs. In 2016, power-injectable PICCs represented less than 50% of the total market for PICCs, with the remaining balance represented by non-power-injectable PICCs. Growth in the unit sales of advanced materials PICCs is expected to drive gains in the share of power-injectable PICCs over the forecast period.
The Japanese market for peripheral intravenous catheters (PIVCs) is split up into two segments: conventional PIVC and safety PIVC. PIVCs are inserted in veins and arteries. An arterial access site is utilized in patients that require blood pressure monitoring. Firmer catheters are preferred for arterial access. A venous access site is utilized for infusing fluids, providing antibiotic treatment and other standard procedures.
The total Japanese market for port needles can be segmented by conventional and safety port needles. In 2016, the largest segment in the total port needle market was the safety port needles. This segment is experiencing higher unit sales growth than the conventional port needle segment; however, this is slightly balanced by more moderate price declines.
