TIssue/Suture Cutting

SYNEO manufactures very precise, super sharp cutting components for medical devices. Our cutters are manufactured to very tight tolerances to ensure repeatability and performance. SYNEO will work closely with customers to design and develop cutter criteria for sharpness, incision dynamics, and durability. We will assist in the selection of stainless steel material, coating options, and heat treatment to achieve optimal cutting performance for the customer's application. We are committed to our customers through the entire process starting with R&D, clinical trials, and commercial production.


SYNEO, the leading edge in medical automation solutions, is pleased to announce the ISO 9001:2015 certification of its Texas manufacturing facility. An ISO certification is a significant achievement as it signifies a commitment to quality, process controls and customer satisfaction.

Anastomotic Connection Devices

Anastomotic coring devices are used during coronary artery bypass to core out a plug of myocardium for insertion of an apical graft. Syneo manufactures coring knives for devices that require a superior cutting edge. We work closely with our customers from the beginning stages to production and offer the sharpest coring components in the industry.

Atherectomy Devices

Atherectomy devices are used to remove plaque build-up in arteries in patients that have peripheral vascular disease. Syneo manufactures these coring components used in directional or rotational atherectomy devices to cut and/or core out plaque to improve blood flow. Our cutters have an optimal cutting edge designed from customer specifications that rival any other cutters in the industry.

Aortic coring cutter

An aortic coring cutter is used to make a circular incision through the left ventricle of the heart during LVAD procedures. The left ventricle is a thick-walled, fibrous chamber of the heart that pumps blood to the aorta and systemic arteries. This fibrous wall demands a very sharp coring cutter to make a clean, precise hole. Syneo cutters undergo a sharpening process that yields an extremely sharp cutting edge.

Breast biopsy

A hollow coring biopsy cutter is used to retrieve small tissue samples from a breast lump to be sent to a pathology lab for examination. It is critical that the cutting edge is super sharp during incision as it promotes less trauma to the tissue and speeds up the recovery time with less scaring. Syneo manufactures biopsy cutters to desired specifications.

Corneal trephine

A corneal trephine is a surgical cutter used in a surgical instrument by an ophthalmologist to remove a circular piece from the cornea during corneal transplant surgery. Corneal transplantation, also known as corneal grafting, is a surgical procedure in which a damaged or diseased cornea is replaced by donated, healthy cornea tissue. Syneo manufactures corneal trephines for surgical instruments to OEM and contract manufacturer specifications and designs.

Suture cutting

The majority of surgical procedures rely upon various types of sutures for not only closing incisions, but also for connecting and/or supporting structures within the body. The use of sutures usually requires the tying of knots, creating suture tails. Syneo manufactures cutting components for suture cutting devices deployed in a variety of surgeries and procedures. We also have the ability to coat our cutters with titanium nitride to withstand the tensile strength and nature of these sutures tails. Our TiN coating protects the cutting edge, which creates durability to withstand multiple cuts.



Inside cutting edge medical punch tip

The inside edge has a straight inside bore diameter and a taper on the outside diameter, which yields a cutting edge at the inside diameter of the punch.


Middle cutting edge medical punch tip

The middle edge is achieved by tapering the outside and inside diameter which yields a cutting edge approximately in the middle of the punch wall.


Outside cutting edge medical punch tip

The outside edge has a straight outside diameter and a taper on the inside bore diameter, which yields a cutting edge at the outside diameter of the punch.






We will work with you to create custom shapes that meet your specific needs.


304 stainless steel

304 stainless steel is the most commonly used material as it is guaranteed to deliver the highest quality product and is suited for a broad range of applications. 304 contains 18 percent chromium and 8 percent nickel, making it ideal for the medical device industry.

17-4PH stainless steel

17-4PH stainless steel is used in multi-use applications in which durability is crucial. It is a precipitation hardening martensitic stainless steel with mechanical properties that can be optimized with heat treatments. 17-4 withstands corrosion more effectively than any other hardenable stainless steel.

465 stainless steel

465 stainless steel is a premium quality, high strength, age-hardening stainless alloy designed for improved notch tensile strength, fracture toughness and fabricability. This alloy has excellent resistance to stress corrosion cracking. 465 is superior to most stainless steels and has been found to be ideal for medical instrumentation.

Titanium nitride

TiN is an extremely hard ceramic material that is applied as a thin coating. TiN is used to harden and protect cutting and sliding surfaces, and as a non-toxic exterior for medical implants. In most applications, a coating less than five micrometers (.00020") is applied. The coating also adds lubricity to the cutter. TiN meets FDA guidelines and is used on medical devices where sharpness and edge retention are a priority.
