Intended Use

The MicroCutter XCHANGE™30 is intended for use in multiple open or minimally invasive surgical procedures for the transection, resection, and/or creation of anastomoses in small and large intestine as well as the transection of the appendix.

Device Story

MicroCutter XCHANGE™ 30 is a single-patient-use surgical stapler. It delivers two double-staggered rows of 316L stainless steel staples while simultaneously transecting tissue. The device features a 30mm staple line and 27mm transection length. It is used in open or minimally invasive surgery by surgeons. The device includes a replaceable cartridge (Blue, 3.5mm staple height for 1.5mm compressed tissue). The subject device modifies the distal tip material of the cartridge insert from liquid crystal polymer (LCP) to polyarylamide. Operation involves manual deployment via the stapler handle. The device provides mechanical tissue closure and transection, aiding in surgical procedures like bowel resection or appendectomy. Benefits include consistent staple formation and tissue transection in a compact, articulated form factor.

Clinical Evidence

Bench testing only. No clinical data required. Verification testing included reliability, bioburden (ANSI/AAMI/ISO 11737-1), shelf-life (ASTM F 1980), and biocompatibility (ISO 10993-1). Tissue leak pressure testing showed no statistical difference compared to the predicate (p>0.05).

Technological Characteristics

Single-patient-use surgical stapler; 316L stainless steel staples; polyarylamide cartridge insert; 340mm shaft; 360° rotation; 160° articulation; 30mm staple line; 27mm transection length; gamma radiation sterilization (SAL 10^-6); MR-conditional; biocompatibility per ISO 10993-1.

Indications for Use

Indicated for patients undergoing open or minimally invasive surgical procedures requiring transection, resection, or anastomosis of the small and large intestine, or transection of the appendix.

Regulatory Classification

Identification

An implantable staple is a staple-like device intended to connect internal tissues to aid healing. It is not absorbable.
