The medical puncturing device (10) includes a housing (12) having a proximal end (18) and a distal end (16) and a skin puncturing assembly (14) within the housing. The skin puncturing assembly includes a movable carrier (50) and a skin puncturing element (52). The skin puncturing element is adapted to puncture the skin of a patient. The carrier is movable from a retracted position wherein a distal tip of the skin puncturing element is disposed within the housing, to a puncturing position wherein the distal tip is exposed to puncture the skin of the patient. The carrier is moved from the retracted position to the puncturing position upon radial deformation of the housing. An internal guide (42) may be provided within the housing for guiding the movement of the carrier from the retracted position to the puncturing position.

A surgical portal apparatus includes a portal, a seal, a plurality of restricting members, and a lockout assembly. The portal defines a longitudinal axis and has a longitudinal opening. The seal is disposed in mechanical cooperation with the portal and defines a passage for reception of a surgical object. The plurality of restricting members are arranged about the longitudinal axis to define a passage therethrough and positioned to contact the surgical object. The restricting members have contacting segments adapted for radial movement relative to the longitudinal axis from a rest position to a displaced position. The lockout assembly includes a locking member disposed distal of the restricting members. The locking member is positioned to intersect the longitudinal opening and engage the surgical object. The locking member is operatively coupled with the restricting members to minimize offset manipulation of the surgical object.

Apparatus and methods enable insertion and tensioned deployment of a secondary material prosthetic device into a body cavity or other tissue of a patient, such as for example hernia repair mesh into the abdominopelvic cavity of a patient through the hernia site. The present invention establishes fixation sites for the prosthetic device and tensions it against the body tissue. It may also be used implant fixation devices within the body tissue so that the prosthetic device is tensioned into firm abutting contact with the body tissue. Instrument deployment and fixation struts may be advanced in retrograde fashion in order to reduce needed deployment volume within the patient's body cavity. The prosthetic device advantageously may be flexibly coupled to the instrument via fixation devices such as sutures, so as to increase orientation flexibility.

The medical puncturing device includes a housing (12), a shield (13), and a skin puncturing assembly disposed within the housing. The shield is axially movable in the housing. The skin puncturing assembly includes a movable carrier and a skin puncturing element mounted to the carrier. A distal end of the skin puncturing element is adapted for puncturing the skin of a patient. The carrier is movable from a retracted position wherein the skin puncturing element is disposed within the shield to a puncturing position wherein the distal end of the skin puncturing element is exposed. The carrier is maintained in the retracted position by engagement of flexure members or a retaining tab with the carrier. A drive spring is provided to move the carrier from the retracted position to the puncturing position. A retraction spring is provided to return the carrier and skin puncturing element into the housing.

Provided is an endoscopic suturing system for joining internal body tissues in a variety of procedures. The system comprises a suturing capsule releasably mountable to the distal end of an endoscope and capable of forming multiple stitches in tissue at a plurality of locations without requiring withdrawal of the capsule from the patient between stitches. Also enclosed is a suture lock to secure the placed stitch that is delivered by a device introduced through the working channel of the indwelling endoscope. Suitable control handles for the suturing capsule and for the suture lock delivery device positioned at the proximal end of the endoscope are provided to facilitate operation by the user.

An internal guide (42) may be provided within the housing for guiding the movement of the carrier from the retracted position to the puncturing position.
摘要:
A seal assembly which includes a housing defining a longitudinal axis, a proximal portion and a distal portion and including a bellows disposed along a length thereof. A first sealing membrane and a second sealing membrane associated with the proximal portion of the housing, each sealing membrane configured to create a substantially fluid-tight seal around a surgical instrument inserted therethrough. The bellows configured to allow at least a portion of the housing to move radially with respect to the longitudinal axis.
摘要:
A suture anchor system for repairing torn or damaged tissue is provided and generally includes a first suture anchor having at least one length of suture attached thereto, and a second suture anchor having at least one length of suture attached thereto. Each length of suture is coupled to one another such that a distance between the first and second suture anchors with respect to each other can be selectively adjustable. The suture anchor system also preferably includes at least one slip knot that allows the first and second suture anchors to be maintained in a fixed position with respect to one another. In use, the suture anchors can be deployed through tissue to be repaired and into the anchoring tissue at a position spaced apart from one another by a selected distance. The suture length(s) can then be tensioned to re-approximate the torn or damaged tissue toward the anchoring tissue, thereby securely attached the torn tissue to the anchoring tissue.
