摘要:
Described herein are methods and devices for loading an anastomotic seal (26) into a delivery lumen. A loading device (28) can fold the seal into a configuration for insertion into the delivery lumen. For example, the loading device can fold the seal into a prolate spheroidal shape. The delivery lumen can then be inserted into the loading device and mated with the folded seal.

Disclosed herein are methods, devices, and systems for folding a sealing element (70). A loader (10, 30, 60) can receive a substantially unfolded sealing element, which when moved through the loader is configured for receipt in an insertion instrument (50). For example, the sealing element can be folded into a substantially prolate spheroidal shape. The folded sealing element can then be inserted into the insertion instrument. In one aspect, the loader is adapted to allow insertion of the folded sealing element into the insertion instrument when the folded sealing element is within a channel of the loader.
摘要:
The present invention provides a surgical device for performing minimally invasive surgical procedures, said device comprising: an elongated body having distal and proximal end portions and at least two lumens extending generally along a direction of a longitudinal axis of said elongated body; and an endoscope positioned in one of said at least two lumens that is configured and dimensioned for receiving said endoscope therein; wherein a distal end of said elongated body extends distally past a distal end of said endoscope to shield said distal end of said endoscope during use.
摘要:
A medical device, such as an intra-aortic balloon pump or carrier with an extendable wheel track and handle configured to be removably carried and integrated with a cart. The wheel track is configured to extend upon extension of the handle and to return to its original position upon retraction of the handle.
摘要:
The present disclosure is generally directed towards methods and devices for reducing or eliminating reflection-illuminated artifacts. The methods and devices in several embodiments can include providing a transparent lens cover with a blocking member for reflecting or absorbing internally-reflected light. The lens cover can be attached at the distal end of an endoscope, cannula, and/or lumen in some embodiments. Alternatively, the lens can be a permanent part of the endoscope, lumen, and/or cannula.

摘要:
A surgical instrument (10, 100) includes a mount body (22, 122), a joint member, an arm, and a working end (14, 114). The mount body (22, 122) has a top portion, a distal end (24, 124), a proximal end and a bottom portion. The joint member is pivotally mounted at a distal end portion (24, 124) of the mount body (22, 122), to allow positioning of a proximal portion of an arm (12, 112) extending distally from the joint member (30, 130). The joint member (30, 130) is also configured to at least partially constrain movement of the proximal portion of the arm (12, 112) to a plane. The working end (30, 130) is mounted to a distal end portion of the arm. The surgical instrument (10, 100) can be configured as a heart stabilizer or a heart positioner. The joint member (30, 130) consists of a slotted ball (36, 136) connected to a disk member (34, 134).
摘要:
A surgical instrument includes an elongated body having a distal end, a proximal end, and a bore extending between the distal and proximal ends, a pair of jaws for severing vessel mounted on the distal end of the body, wherein at least one of the jaws has an electrically conductive material, and a handle coupled to the proximal end of the elongated body, wherein in a first mode of operation, the electrically conductive material is for receiving energy from a DC source, and in a second mode of operation, the electrically conductive material is for receiving energy from a RF source.
