A delivery system includes a catheter with a removable constraint. The removable constraint is a knit tubular construct. The removable constraint can be used, for example, to constrain a medical device to a delivery configuration. The removable constraint may include one or more fibers or strands arranged about the device to maintain the device in a constrained or delivery configuration.

A medical instrument and method for producing a medical instrument. The medical instrument includes at least one instrument arm. A toothing with at least two teeth is formed on a distal end of the instrument arm. Each of the teeth project transversely from the distal end and has two tooth flanks facing away from one another. Each tooth flank has at least one planar first surface region and at least one planar second surface region. The at least one planar first surface region and the at least one planar second surface region are inclined toward one another by a surface to region angle. The first and second surface regions are formed by milling, in particular with a CNC machine.

A biomimetic tissue scaffold for repairing an elongated tissue in need of repair can comprise a plurality of coiled flexible polymeric ribbons having a surface on which is formed an array of nanofibers, the ribbons forming a tubular body defining a first open end in which a first end of the elongated tissue is receivable, a second open end in which a second end of the elongated tissue is receivable, and a lumen extending between the first and second open ends.

A device and method for cutting or ablating tissue in a human or veterinary patient includes an elongate probe having a distal end, a tissue cutting or ablating apparatus located adjacent within the distal end, and a tissue protector extending from the distal end. The protector generally has a first side and a second side and the tissue cutting or ablating apparatus is located adjacent to the first side thereof. The distal end is structured to be advanceable into tissue or otherwise placed and positioned within the patient's body such that tissue adjacent to the first side of the protector is cut away or ablated by the tissue cutting or ablation apparatus while tissue that is adjacent to the second side of the protector is not substantially damaged by the tissue cutting or ablating apparatus.

The present invention relates to a tube member having excellent local bending properties that is capable of being freely bent only on a given region thereof at a working temperature, thereby enabling the bending angle thereof to be freely adjusted by a user, and a method for manufacturing the tube member. According to the present invention, the tube member having excellent local bending properties, which is made of an alloy, may include a first region and a second region having different alloy structures from each other. According to the present invention, the first region may be in a cold-worked state or have an austenite phase at a given working temperature, and the second region may have a martensite phase at the given working temperature and a yield stress value lower than a yield stress value of the first region.

An electrosurgical electrode (30) includes a conductive rod (32) having a working portion (38) at a distal end portion (35). The electrode (30) also includes a composite coating (40) disposed on the working portion (38). The composite coating (40) includes a first coating (42) disposed on an outer surface of the working portion (38) and a second coating (44) disposed over the first coating (42).

A surgical cutting and stapling end effector. Various embodiments comprise a channel that is configured to operably support a removable staple cartridge. A rotary end effector drive shaft is supported within the channel and is configured to move a firing assembly longitudinally within the end effector to cause the sled to eject surgical staples from the staple cartridge. The firing assembly is prevented from moving distally through the channel unless a surgical staple cartridge that has a sled in a starting position has been seated within the channel.

The disclosed technology includes a medical probe comprising a tubular shaft having a proximal end and a distal end, the tubular shaft extending along a longitudinal axis. The medical probe further comprises an expandable basket assembly coupled to the distal end of the tubular shaft. The basket assembly includes a plurality of electrodes with each electrode of the plurality of electrodes having a lumen therethrough. The basket assembly further includes a plurality of spines extending along the longitudinal axis and configured to bow radially outward from the longitudinal axis when the expandable basket assembly is transitioned from a collapsed form to an expanded form. Each spine includes a proximal and a distal end and a strut passing through the lumen of an electrode. The strut includes a mechanical retainer disposed on the strut to prevent the electrode from sliding proximally or distally along a length of the spine.

The disclosed technology includes a medical probe comprising a tubular shaft extending along a longitudinal axis and including a proximal end and a distal end. The medical probe further comprises an expandable basket assembly proximate the distal end of the tubular shaft. The basket assembly comprises a plurality of C-shaped spines and one or more electrodes coupled to each of the spines, each electrode defining a lumen through the electrode so that a spine extends through the lumen of each of the one or more electrodes. The spines converge at a central spine intersection at a distal end of the basket assembly. Each spine comprises a respective end connected to the distal end of the tubular shaft.

An apparatus for rolling a bladder includes a support structure, a rolling pin, and a bladder-mounting pin. The apparatus optionally includes a rolling initiator Rolling a bladder includes inserting the bladder while unrolled into an apparatus for rolling a bladder, inserting the bladder between a rolling pin and a bladder-mounting pin of the rolling machine, and rotating the rolling pin to (a) advance a portion of the bladder between the rolling pin and the bladder-mounting pin, (b) roll the portion of the bladder around the bladder-mounting pin, and (c) drive the bladder-mounting pin to rotate in an opposite direction from that of the rolling pin.
