The second section of the cannula is of a material that is softer and/or more flexible than that of the first section. By being composed of a softer and/or more flexible material, the second section of the cannula can be maintained adjacent to or abut internal organs during and after a surgical procedure. In some cases, the improved trocar can have a cannula comprised of a single material such as rubber or silicone. The improved trocar can be safely maintained in a patient for a certain duration following a surgical procedure, such as after deflating the abdominal cavity in a laparoscopic procedure or after closing an incision in an open surgery. In some cases, the trocar cannula can be safely maintained in a patient up to seven days after completing a surgical procedure. | 12-16-2010 |
20100324488 | TROCAR ASSEMBLY WITH OBTURATOR AND RETRACTABLE STYLET - A surgical system for penetrating tissue includes an obturator having an obturator housing and an obturator member extending from the obturator housing and having a penetrating member adapted to penetrate tissue. The penetrating member defines an outer wall with an irregular surface dimensioned to facilitate passage through tissue. The obturator may further include a stylet at least partially disposed within the obturator member. The stylet and the obturator member are adapted for relative longitudinal movement between a first relative position corresponding to an unarmed condition of the penetrating member and a second relative position corresponding to an armed condition of the penetrating member. | 12-23-2010 |
20120059324 | SURGICAL ACCESS PORT AND METHOD OF USING SAME - A surgical access port for insertion into a body cavity can have an elongate tubular body extending along an axis between a proximal end and a distal end, and a tip at the distal end of the tubular body for penetrating through a body wall and into the body cavity. The distal tip moves from a first, penetrating position to a second, retaining position when the body wall has been traversed. The surgical access port may further comprise a seal housing connected to the proximal end of the tubular body, the seal housing having an access port providing an opening into the tubular body to allow passage of surgical instruments. The distal tip may be sharp, pointed or bladed. The distal tip may also be substantially blunt or have a conical surface. The access port may further comprise a retention member for connecting the tubular body and the distal tip. | 03-08-2012 |
20120209203 | MEDICAL DEVICE FOR APPLYING CATHETERS, PARTICULARLY FOR THORACENTESIS PROCEDURES - A medical device for applying catheters, particularly for thoracentesis procedures, comprising a hollow supporting element which can be gripped ergonomically and accommodates a selector which is adapted to connect at least three openings defined in the supporting element, the first opening being functionally associated with a cannula adapted to be inserted in the body of a patient, the second opening and the third opening being able to be functionally associated respectively with two closure elements or with at least one of a syringe and a collection bag, a sharp-tipped needle being slidingly insertable in the cannula and having such a length as to pass through at least all of the cannula and protrude from it, the device further comprising a fourth opening defined in the supporting element on the side opposite the first opening for extraction or insertion of the sharp-tipped needle respectively from and into the cannula. | 08-16-2012 |
20120245526 | LOW PROFILE INTRODUCER APPARATUS - An introducer apparatus includes an outer sleeve and an inner cannula received within the lumen of the outer sleeve. The outer sleeve has a profile such that at least a portion of the distal end of the outer sleeve tapers in the distal direction at an angle not exceeding about 2° relative to a longitudinal axis of the apparatus. The distal open end of the outer sleeve has a wall thickness not exceeding about 0.003 inch. The inner cannula includes a tapered distal end portion. The tapered distal portion of the inner cannula extends distal to the distal open end of the outer sleeve, such that a generally smooth diametrical transition is provided between the outer sleeve tapered portion and the open distal end of the inner cannula. | 09-27-2012 |
20130030372 | Trocar Seal with Retraction Induced Hinge - A trocar comprising an alignment channel and an instrument seal comprising a bending portion and a base portion.
