Cardiovascular components for medical devices.Complex Cardiovascular Components

Cardiovascular components for surgical devices are complex. Cadence has been the supplier of choice for incision components used in the cardiovascular market for many years. Our breadth of experience in this market allows us to work closely with medical device OEMs in a way that fully enables innovative and highly specialized cardiovascular solutions.

  • Cadence acts as a trusted OEM partner in developing, manufacturing and assembling numerous cutting and piercing components and assemblies used in the following areas:
    • Cardiac surgery
    • Interventional cardiology, neurology, and neurostimulation
    • Peripheral vascular
    • Cardiology and radiology
    • Cardiac rhythm management (CRM)
  • Some of the more common Cardiovascular procedures requiring critical incision components are:
    • Coronary artery bypass (on and off-pump)
    • Valve repair and replacement
    • Congenital cardiac repairs
    • Minimally invasive robotic-assisted heart surgery
    • Surgical ablation for atrial fibrillation
    • Surgical ventricular remodeling
    • Catheter ablation and pulmonary vein ablation
    • Cardiac transplantation

These cardiovascular procedures demand components with the highest precision and reliability. These products are often manufactured from the most specialized metals, such as Nitinol. Our customers come to us looking for the knowledge base we have surrounding incision technology and find our “Center of Excellence” for incision applications to be compelling and a cornerstone of future partnerships.

Cardiovascular Precision Component Production

Cardiovascular devices demand some of the toughest tolerance requirements and smallest design windows. This combination can be a recipe for disaster. However, partnering with the leading medical device OEMs has helped us more fully understand the design needs of the surgical device designer and the manufacturing processes requirement to produce precision components on a production basis. From tissue cutters to aortic punches and from trocars to bipolar cutting forceps and endoscopic scissors, all incision components are manufactured to customer-supplied specifications, which are protected by our strict employee code of confidentiality.

Cadence solves blood vessel cutting problem created by stamping house - Due to the fast pace of new cardiovascular medical device development, true optimized cutting performance is usually either a total afterthought or only brought to the attention of the design team after initial functional failures in testing. During a recent product launch, Cadence was contacted for guidance relating to poor cutting performance in a new medical device. Following in-depth analysis in our IncisionLab™of current blades, it became apparent that the cutting edge was simply not sharp enough to perform the task.

A review of the current manufacturing process revealed that the cutting edges were being generated on a grinder at a local stamping company. This process generated a large amount of burr that was being only partially removed during a manual buffing process, done as a secondary operation.

Cadence produced a lot of blades utilizing its proprietary CNC sharpening processes in concert with the IncisionLab™. The functional results of more precise cutting edges were dramatic! The problems associated with cutting were totally eliminated along with the concerns about product consistency. An added benefit to this solution was a lower total cost to the medical device OEM due to the reduction of scrap and the elimination of a secondary deburring process.
